A metal carbonate X on reacting with an acid gives a gas which when passed through a solution gives the carbonate black. On the other hand, A gas G that is obtained at anode during electrolysis of brine is passed on dry Y, it gives compound Z, used for disinfecting water. Identify X, Y, G and Z.

A metal carbonate X, and a metal bicarbonate Y on reacting with an acid gives a gas which turns lime water milky. Identify the gas, compound X and Y.

A metal carbonate X, and a metal bicarbonate Y on reacting with an acid gives a gas which turns lime water milky. Write the chemical equatins for the reaction of X and Y with the acid.

When electricity is passed through a common salt solution, sodium hydroxide is produced along with the liberation of two gases 'X' and 'Y' The gas X burns with a pop sound whereas 'Y' is used for disinfecting drinking water. Identify X and Y.

A metal carbonate X, and a metal bicarbonate Y on reacting with an acid gives a gas which turns lime water milky. What would happen if you pass excess of this gas through water? Write the chemical equation for it?

When electricity is passed through a common salt solution, sodium hydroxide is produced along with the liberation of two gases 'X' and 'Y' The gas X burns with a pop sound whereas 'Y' is used for disinfecting drinking water. State the reaction of Y with slaked lime.

A non-metal A which is the largest consituent of air, when heated with H_2 in 1:3 ratio in the presence of catalyst gives a gas B. on heating with O_2 it gives an oxide C. If this oxide is passed into water in the presence of air it gives an acid D which acts as a strong oxidising agent. Identify A,B,C and D.

A water soluble compound 'X' of sodium on reacting with dil. H_2SO_4 released a colourless gas accompanied by brisk effervescence. When the gas was passed through water, the solution obtained turned blue litmus solution red. On bubling the gas through lime water, it initially became milky and the milkness disappeared when the gas was passed in excess. Identify the substance 'X' and write the chemical equation for the reactions involved.

Aniline is treated with bromine water to give an organic compound ‘X’ which when treated with NaNO_2 and HCl at 0^@C gives a water soluble compound ‘Y’. Compound ‘Y’ on treatment with Cu_2Cl_2 and HCl gives compound ‘Z’. Compound ‘Z’ is F

Aniline is treated with NaNO_2//HCl at 0^@C to give compound X which on treatment with cuprous cyanide gives another compound Y. When compound Y is treated with H_2//Ni compound Z is obtained. The compound Z is

An orange solid A on heating gives a colourless gas B. The gas B in dry conditions is Passed Over heated Ca to give a solid C. The solid C further reacts with water to Produce gas D which forms a blue coloured compound E on reaction with copper sulphate solution. Identify A, B,C,D,E and give the sequence of reactions involved .
